Write four paragraphs to define the term 'physical computing'. (4 paragraphs)
Physical computing is the computerization of physical objects. In other words, it transforms intangible objects into tangible objects. Thus, it is a translation of sensory input through the computerization of information pieces.
Physical computing introduces a new form of human interaction. This enables users a way to visualize an action without actually performing it. It is a way to really see what you are doing.
In the Sixth Sense video, a sixth human sense is added. This extra sense provides an opportunity for instant information on just about anything via the internet. Having a flat surface is the only requirement for this sense to be used alongside with natural hand gestures. It is a wearable gestural interface in which uses a camera and a tiny projector. Through this interface, information is projected onto a surface and is controlled by hand gestures.
The multisensory potential of digital technology can be further explained through the demonstration of Hiroshi Ishii’s music bottles project. This project uses sound to portray different meanings to its user. Ishii states that the object serves as a control mechanism/direct manipulation of input representations. It does this by the tangible interactions that the user may engage in.
Write two paragraphs each describing their prototyping methods, and describing what they are enabled to do. (4 paragraphs)
d.tools: Reflective Physical Prototyping
The reflective physical prototyping method involves a small LCD screen, an accelerometer, a d.tools hardware interface kit, and a computer. Visual counterparts in the d.tools authorizing environment would appear as physical components are plugged in. D.tools assists in the designing, testing, and analysis of devices.
Orientation sensors in a handheld GPS system allow users to navigate through maps by simple hand movements. The map can be navigated by tilting the device left or right. This movement moves the map to the corresponding side. This form of prototyping allows the designer to learn how effective the functionality of their design is.
Exemplar: Authoring Sensor-based Interactions by Demonstration
This is the exploration and prototyping that involve sensors. This is done by using a 3D accelerometer and a compatible hardware interface. Exemplar generates events based on matching regions as actions are recognized and outputted onto the computer screen. Thresholds are made by the designer depending on what actions are to be recognized by the device. Ranges can also be programmed through thresholds.
Movements can be recognized through sensors. Through the lane change signals on the bicycle helmet, users can signal their direction by tilting their head to the corresponding side. Tilting left is associated with turning left and vice versa.
